How to run TurboTax online?
One of the people from TurboTax said in response to a Linux user:
[...]you can try the link below to bypass TurboTax's system requirement checks. We can't make any guarantees that you won't run into problems though.

Trick turbo tax into thinking you're on Windows 7 64 bit with IE9:

Check out the last section called "Mozilla Firefox"
Navigate to
about:config
Accept the warning
Create a new string called
general.useragent.override
Set the value to
Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
Close out of firefox and revisit turbotax
Log in and finish taxes
If that doesn't work out for you TaxAct.com does work with Linux and has comparable features to TurboTax.
